3 1. Urban context Population growth of Tampere Sustainable urban densification Tampere, Tammela district Site

4 Population growth of Tampere 160, , , , , WHY? Urban densification and complementary urban in-fill Current developments of increasing URBANIZATION demands strategies Densification is a concept for more SUSTAINABLE and greener cities CLOSER distances, more public transport LESS energy, traffic and emission Taking advantage of existing INFRASTRUCTURES without territorial extension

5 City of Tampere Possible sites for urban in-fill on rooftops

10 2. Concept & plans Rooftop extension Approach & development Concept, form and function Floorplans Elevations & sections

11 Rooftop extension First approach: Replacing the attic floor, made from concrete elements, with approximately 5 times the amount of wooden construction. - Timber weights about one fifth of reinforced concrete - Basic semi privat Corridor Corridor with lightshafts and entrance hubs Shaping 1. step Shaping 2. step 3. Step subtraction of corridor and light shafts Diagonal LINES, connecting all staircases CORRIDOR ALLEY with skylights and entrance hubs 4. Step Division into apartment units Approach: Structure and apartment division, based on the wall structure of the existing buildings Existing walls New walls first floor New walls second floor Open view in both directions on the second floor Approach & shape development

12 Dwellings combination concept Dwellings by Type of Building, Tampere Block of Flats Detached Houses Terraced Houses Others 73% (91,000) 14% (18,090) 11% (13,118) 2% (2,859) Spatial functions, forms and sizes of the individual Apartments Duplex Apartments Community Sauna Sauna 48m 2 5 Rooms 100m 2 Sauna 48m 2 4 Rooms 107m 2 4 Rooms 94m 2 4 Rooms 92m 2 3 Rooms 91m 2 + Loft 4 Rooms 104m 2 + Loft Schematic floor plans First floor Second floor 5 Rooms 109m 2 4 Rooms 99m 2 5 Rooms 114m 2 5 Rooms 115m 2

13 Rooftop extension Corridor alley: To connect all apartments with the staircases, terraces and the roof garden, a corridor passes through the structure that appears like a semi private alley and can be used by all housing residents. From there entrance hubs lead to every new duplex house. Light shafts and skylights provide daylight for the alley as well as for the apartments, which have internal windows towards the light shafts and alley. Apartments: 10 individual duplex apartments comparable to terraced houses are added on the existing building structure. All houses are designed very open with a lot of glazed façade that can be individually transformed by moveable shading elements to vary the degree of open- and closeness as needed and pleased. Additionally the second level of all houses is opening up to east and west to allow for as much daylight and view as possible. Roof garden and terrace spaces: Approximately 750m2 terrace and roof garden is proposed on the attached building roof at the southern end of the long existing building structure. Accessible for all building inhabitants, it serves like a common yard and offers possibilities for urban gardening, sun bathing, playing and relaxing. Furthermore the green roof not only provides benefits for a more livable environment and a more greener and sustainable development, it can as well provide better insulation for the building below. Functions & Benefits External staircase and Elevator: The additional external circulation provides an independent access to the roof top extension structure without disturbance of the existing structure and residents. It can as well function as an extra fire escape route for safety purposes. Community sauna: To provide the same amenity that is currently located in the attic, each building has a new community sauna with balcony integrated to the new structure facing to the west towards the greener side of the plot and to make most of the sun and sunset over the city.

21 WHY? Wood and timber construction NATURAL, most sustainable and climate friendly LOW energy effort to achieve construction material Sense APPEALING features- pleasant to look and touch Holistic APPLICATIONS Breathing capacity provides good indoor CLIMATE Light, EASY to handle and warm LOCAL and traditional building material of Finland PREFABRICATION - for fast, precise and disruption-less assembly at site Possibility of RECYCLING

22 Timber construction method From rods to planes and to 3D systems High degree of prefabrication and high freedom in design with customized 3D units Assembly of single components Combination of parts Prefabricated Prefabricated modules Prefabricated units and elements wall/ floor elements Degree of prefabrication Degree of prefabrication low low From raw to ready-made Different levels of prefabriaction Freedom of design opportunities high Different levels of prefabriaction high low high high Freedom of design opportunities Grade of pre-manufacturing Flexibility of Material Customization
